Letters Patent No. 91,748, dated June 22, 1869.

IMPROVEMENT IN PAPER BAGS AND MATERIAL THEREFOR.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, ABIEZER JAMESON, oi'Trenton, New Jersey, have invented an Improved Bag; and I do herebydeclare the following to be a full. clear, and exact description of thesame.

My invention consists of a bag, made ofxa fabric composed of paper andtextile fabric, or fibrous strands combined, as fully describedhereafter, the said bag being much stronger and more durable `than theordinary paper bags, for which it is intended as a 'substitute.

In order to enable others to manufacture my invention, I will nowproceed to describe the manner in which the same is made, referencebeing had to the accompanying drawing, which forms a part of this'specication, and in which- Figure l is a perspective view, partly insection, of my improved bag;

Figure 2, an inverted plan view; and

Figure 3, an enlarged sectional view of the fabric of which the bag ismade.

A light textile fabric, aand sheets ot paper b b, are combined, byinserting the fabric between the sheets of paper while the latter are ina soft or pulpy state, and passing the whole between pressure-rolls; andthe fabric thus made is then cut and pasted, so as to form a bag, A, oi'the size and shape desired.

A bag made as above described is much stronger and more durable than theordinary paper bags, for which it is intended as a substitute, and maybe made at little if any additionalcost, as, owing to the combination ofthe textile fabric with the paper, the latter may be much inferior inquality to and lighter in weight than the paper which would otherwise berequired to form a bag of the desired strength, while the combination ofthe fabric and paper may be effected at but a slight expense.

In place of a textile fabric, fibrous strands may be embedded in thepaper to strengthen the latter, the fibres being formed into a-sheet onanordinary carding-machine, and being then combined with 'the paper inthe same manner as the fabric, or during the process of the manufactureof the paper.

I am aware that'wrappers, 85e., have been made from a materialconsisting of sheets of paper pasted to textile fabrics; but asubstitute for paper bags cannot be made from such a material, as, apartfrom the expense of manufacturing it, the paper must be heavy to retainthe paste, thus rendering the fabric liable to break when folded, whilethe paste renders the fabric stiii` and unyielding, so that it isdif'cult to make it in'to'bags.

A bag formed from a material consisting lof a light fabric or fibrousstrands embeddedI in pulp, or in paper, during the process ofmanufacturing the same, is soft and yielding, light in weight, and muchstronger than bags made of the ordinary paper.

The vbags also may be as readilymanufactured from this material as frompaper, While they willfnot break,

like thelatter, should they become dampened.

Without claiming broadly, therefore, a bag made oi' a materialconsisting of paper and textilefabric,

I claim as my invention, and desire to secure by Letters Patent- A bagconsisting of a material made by embedding fibrous strands in paperwhile the latter is in a pulpy condition, as described.

In testimony wheref, I have signed my name to this specification, in thepresence of two subscribing witnesses.

ABIEZER JAMESON.
